/*
  Based on AliPHOSQADataMaker
  Produces the data needed to calculate the quality assurance. 
  All data must be mergeable objects.
  P. Christiansen, Lund, January 2008
*/

/*
  Implementation:

  We have chosen to have the histograms as non-persistent meber to
  allow better debugging. In the copy constructor we then have to
  assign the pointers to the existing histograms in the copied
  list. This have been implemented but not tested.

  For the QA of the RAW data we use the class, AliTPCdataQA, from the
  existing TPC Calibration framework (which is more advanced than the
  standard QA framework) and extract the histograms at the end. This
  has been tested with zero-suppressed data. The Analyse method of the
  AliTPCdataQA class is called in the method, EndOfDetectorCycle, and
  there also: 1d histogram(s) are projected and added to the QA list.

  Sumw2 for RAW histogram(s)?
